We present a mathematical model for a study of the mechanical properties of endovascular stents in their expanded state. The model is based on the theory of slender curved rods. Stent struts are modeled as linearly elastic curved rods that satisfy the kinematic and dynamic contact conditions at the “vertices” where the struts meet. This defines a stent as a mesh of curved rods. A weak formulation for the stent problem is defined and a finite element method for a numerical computation of its… CONTINUE READING
